MIXING nnvrcn.

Application filed April 30, 1925. Serial No. 26,988.

The present invention appertains to new and useful improvements in mixing dev ces for internal combustion engines,

primary object of the invention is the pro-' vision of means for supplying moisture or mo stened, air to the explosive mixture-as it passes from the carburetor to the intake manifold of the internal combustion engine.

Another very important object of the in-' ingly increasing the eificiency of the enginewhile' tending'tocool the engine cylinders, as well as deter the the firing chambers of the cylinders.

Another important object of the invention is to provide an attachment of this nature I which is adaptable foruse in connection with sides in certain novel ,i eatures of construethe various makes of engines as now-upon the market.

Another important object of the invention is to provide an attachment of this nature which may be incorporated in the assembly of the engine without the necessity of providing any holes in the radiator, or other alterationswhich, through the vibration of the engine would 'tend to cause leaks in time. A still further very important objectof the invention is to provide anattachnient of this nature which is exceedingly'simplein its construction, efiicient and reliable in use, inexpensive to manufacture-and install, not liable to readily get outof order, and otherwise welladapted to-the purpose for which it is designed.

Another specific object or" the invention is to provide a value in an attachment of this nature so that the amount of the moistened air maybe controlled as may be desired.

With the above and numerous other and -l incidental ob ects in View, the invention retion, and in-the combination and arrange merit of arts as 'Wlll be hereinafter more rully described and claimed. linthe drawingz Figure l is a side elevation or an internal and the formation or carbon in the connection and continues combustion engine and radiator with my improved attachment associated therewith.

Figure 2 is a sectional View through the body portion, and

Figure 8 is another taken atright angles ure 2.

Referring to the drawing iii-detail, it will sectional view thereof be seen that-A designates generally my improved mixing device which is constructed as an independent and detachable unit adapted to be interposed between the can buretor and the intake manifold as is shown in Figure 1. The

body portion 10 of the to that shown in Figmixing device is preferably formed of metal orpther suitable material and is preferably either elliptical or rhombic shaped in plan. view to correspond in general outline to the outline of the flanges 11' and 12 oi the can buretor 13 and intake manifold 14 respectively, between which it is to be connected. For this purpose, it is provided adjacent its ends with bolt receiving bores 15 through which bo ts 16 may be applied to secure it in place. This body member is provided centrally with a gas opening or passage 1? substantially equal in diameter to the inter nal diameter of the outlet passage of the carburetor and the intake passage of the manifold, and so disposed with respect to the bores 15 as to extend in alignment with said passages and in effect form a continuation. oi them. As is best shown in Figure 3, this passage is somewhat enlarged adjacent one side to provide a stop shoulder 18. Anew ternally threaded nipple 19 extends down-' wardly from the body A and the passage or bore 20 thereof communicates with the passage 17.

A ring 21 is adapted to be received in the enlarged portion of the passage 17, and to hold a screen or sheet of foramincus material 22 against the shoulder 18 so as to ex tend across the intermediate portion of the passage. lhe ring21 is provided with an. outer annular peripheral grbove 23 from which extend openings 9/ disposed radially of the ring, and extending through the interior periphery thereof.

,A pipe P is mounted in the upper TQSQY"; voir of the radiator R. and extends down wardly through the connection U and pierces as at P ham ing a valve V on the end thereoi which is in turn connected to an elbow coupling E which. is engaged with the nipple The mount loosen the pipe so' as to cause leaks as is the for adding and thoroughly mixing moistened air with Le' explosive mlxture casein similar devices with which I ani fa miliar. When the 'valve V is opened, or'parreservoir of the radiator R will be sucked through the pipe P-P, through the valve V, through the coupling E, through the nipple- 19, through the groove 23 of the ring21 and through the openings 24 into the pas sage 17. The carbureted gas will be broken up by the screen 22 so as to be thoroughly mixed'with the moist air, and the mixture of the carbureted gas and moist air will be sucked through the intake manifold 14 in the usual manner.

My improved device may be readily attached to any motor vehicle gas engines now in use without any changes, as practically all such engines are provided with the conventional parts described such as the carburetor, the intake manifold, the radiator, and the connection 0,. By providing means from the carburetor, I prevent the formation of carbon in the motor, and upon the spark'plu'g, and also increase the life of lubricating oil used in the cylinders and' valves. As a result, the motor is smoother j runnm and more powerful than would otherwise e the case. Other advantages will be apparent to those-skilled in the art, and it is thought that the construction and operation will be' clearly understood without a the.

.merely byway of example, and it is apparent'that numerous changes in the details of construction, and in the, combination and arg rangement of parts may be resorted to withtially opened, the moistened air from the v outjdeparting from the spirit or scopeof the invention as hereinafterclalmed or sacrificing any of its advantages...

, Hav ng thus described the invention, what 'I claim as new and desire to secure by Letar raamsgisae 1. Asa new article of manufacture, a mixing devicein'cluding a body having a pas-- sage-thereimand a nipple. extending from the bodyand having a ore communicating radiallywith'tlie passage, a ring disposed in the "passage having an exterior annular groove communicating with the bore of the nipple and-1a plurality of apertures-extending fromthe grlooveinto the passagei 2.' As anew article of manufacture, a mixing' device including a body having a passage therein, and a nipple extending from the body and-having-a bore communicating QradiaIIyWith the passage, a ring disposed in the passage. having an exterior annular groove communicating with the bore of the nipple and a plurality'of apertures extending from the groove into the passage, said" passage bein enlarged to receive the ring,

and form a s oulder, a sheet of fora-ruinous material extending across the passage held in place against the shoulder by the ring;

In testimony whereof I aflix my signa CHARLESW. 'r oW LnJ a
